Multiple IP Address polling support for a single node

It is taken from a feature request from Questionario. By the way we need this badly.

Re: Feature Request: Multiple IPs per Node

Hi, right now I have several nodes double and triple for monitoring purposes.

One would be the standard Management VLAN IP, another for OSPF and another for a backup tunnel (which is constantly up)

now the management IP is reachable as long as one of these still work but I want to be notified if either of them goes down as well.

I dont need to get performance reports about each single IP but still get notifications if the IP on the node is unreachable!

So it would be a nice enhancement to simply add more "secondary" IPs to nodes without having to create another object (Its not about the licenses but about the manageability).

  • Maybe I'm being dense, but how is this different than monitoring the up/down status of the interface itself?

    We have (you guessed it, it is ME after all) a custom property for each interface that indicates whether we want an alert for up/down status or not (actually, it's a dropdown that lists WAN, CELL, UPLINK, and OTHER). That way we have several alerts keyed to that field

    IF the interface status = DOWN

    AND the interfaces.ALERT = WAN (or cell, or whatever)

    So we can set different delays, destinations, etc for each interface type.

    How would that differ from what you are suggesting?

    Just because an interface is up from the inside of a device does not mean it is accessible from the outside.

    So if a multi homed host is showing all interfaces up but there is a routing problem elsewhere you may not be able to ping one of the interfaces and therefore that ability lets you know that something is broken.

    Helps in troubleshooting.

    For example, a remote site with a primary router and a backup router. If the backup provider's link goes down, their modem may still keep the Ethernet up -- so all your interfaces are up, but one of the IPs is now not reachable because the provider line is down.

    We'd also very much like to have this feature.
